pyOCCT

Modern open-source Python bindings to the OCCT geometry kernel via pybind11.

pyOCCT exposes the OCCT C++ kernel to Python through pybind11. Started in 2017 to track newer OCCT releases and to give consumers a leaner binding layer suitable for CAD/CAE/CAM application development. Drives projects like AFEM, pySMESH, and DeclaraCAD; used by aerospace, mechanical engineering, architecture, and industrial-design teams.
